[4.0.x] Fixed #33462 -- Fixed migration crash when altering type of primary key with MTI and foreign key.
This prevents duplicated operations when altering type of primary key
with MTI and foreign key. Previously, a foreign key to the base model
was added twice, once directly and once by the inheritance model.
Thanks bcail for the report.
Regression in 325d7710ce9f6155bb55610ad6b4580d31263557.
